Application filed May 20, 1914. Serial No. 839,851. 1

To all whom it may concern:

Be it known that I, JAMns Born, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have inventednew and useful Improvements in Screws, of which the following is aspecification.

This invent-ion relates to screws and in particular to those commonlyknown as stage screws. The primary object being to provide a device ofthis character which consists of a body for permanent use and means forsecuring an ordinary wood screw thereto, in order that the screw may bereplaced when worn or broken without 113V".

ing to discard the body of the screw.

A further object of the invention is to provide a screw of this classwhose body portion is constructed in such a manner that it may be usedas a cork screw, a screw driver, a wrench, and in various othercapacities.

The invention consists in the features of construction, combination, andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accompanying drawing, in which:

Figure 1 is a side elevation of the body of the device, showinganordinary wood screw connectedtherewith; Fig. 2 is a longitudinalsectional view on line 22 of Fig. 1; Fig. 3 is a transverse sectionalview on-line 83 of Fig. 2; Fig. 4 is a side elevation of a cork-screwadapted to be applied to the body; Fig. 5 is a similar view of ascrewdriver which isadapted for the same use; Fig. 6 is alongitudinalsectional view through a portion of a modified form of screw body; and,Fig. 7 is a longitudinal sectional view on line 77 of Fig. 6.

In the drawings, the numeral 1 designates the body portion of thedevice, which is provided at itsupper end with oppositely extending,lateral wings 2 which permit the body to be grasped securely whenoperating.

the same. The body is provided medially with a longitudinal slot 3opening through the opposite side faces thereof. A longitudinal opening41 is provided in the lower end of the body in communication with theslot for the reception of the shank of an ordinary wood screw, such asis indicated by the numeral 5. The threaded portion 6 of the screw isadapted to project outwardly from the body, whereas its head 7 iscountersunk within the inner end of the body opening 4.

gagem'ent within the head kerf of the screw -5, whereby the latter willbe held against rotation in its connection with the body. An

operating screw 12 is rota tably mounted within the body opening v ithits head 13 disposed .eXteriorly thereof and with its innerend engagedwithin a socket 14 which is provided in the upper end of the securingmember. The screw 12 extends through a threaded nut 15, which is mountedwithin the upper end of the body slot 8 and is held against rotationowing to its snug fit within the socket. Instead of providing the nut15, the screw body may be modified, as shown particularly in Fig. 6. byproviding a threaded opening in the upper end of the body incommunication with the slot for the reception of the screw.

The body slot 3 is constructed of such length as to permit theintroduction of the replaceable wood screw into the same when mountingthe screw within the opening 4;. When it is desired to remove thesecuring member for the purpose of repair or to clean the same, theoperating screw is withdrawn, whereupon the securing member may beremoved through the body opening 13 and the extensions of the grooves 8.

In order that the body of the screw may be used also as a wrench forturning certain kinds of tools, non-circular openings 16 are providedinits wings. A screw driver extension 17 also is formed upon the outerend of one wing, and a tack-pulling extension 18 is formed upon theopposite wing, in order that the body may be used in the furthercapacities of screw. driver and tack puller. In Fig. 4, a cork-screw isshown constructed for use in the body of the device, and in Fig. 5 ascrew driver is shown constructed for like use.

From the foregoing description, taken in connection with theaccompanying drawings, it'should be apparent that I have provided astage screw which is adapted to be used for a long period of time, itbeing necessary merely to replace the wood-screws, used in connectiontherewlth, as they become worn or otherwlse damaged. The

body of the deviceis also constructed so, that it may be used forseveral difierent purposes in stage work.

--What is claimed is:

1. In a device of the class described, the combination with a rotatableelement having a head, of a body having an opening therein for thereception of the said element, a securing member mounted movably withinthe body and having one edge adapted for engagement with the head tosecure the element against movement within the body, the said securingmember being longitudinally notable with respect to the said element,and an operating screw adjustably mounted within the body in axialaiinement with the securing member for engagement with the end thereofopposite to the edge engaged with the said element.

In a device of the class described, the

combination with a rotatable element having a head, of a body providedwith an elongated slot and with an opening therein in registration withone end of the slot for the reception of the said element, the sidewalls of the said slot being provided with longitudinal grooves, and asecuring member mounted within the body slot with its side edgesslidably engaged within the grooves, one end of the securing memberbeing adapted for engagement with the head of the said element to securethe same against movement within the body, the body being providedfurther with an opening in communication with the opposite end of thesaid slot for passage of the securing member therethrough.

In testimony whereof I afiix my signature in presence of two witnesses.
